Abstract

A vibration based power generator. In a described embodiment, an electrical power generating system includes a vibrating assembly including a vortex shedding device which sheds vortices in response to fluid flow across the vibrating assembly. A generator generates electrical power in response to vibration of the vibrating assembly. The vortex shedding device sheds the vortices at a frequency which is substantially equal to a resonant frequency of the vibrating assembly.
